这是我的数据库

return [ 'class' => 'yii\db\Connection', 'driverName' => 'mysql', 'dsn' => 'mysql:host=localhost;dbname=yii', 'username' => 'root', 'password' => '', 'charset' => 'utf8',
// Schema cache options (for production environment)
//'enableSchemaCache' => true,
//'schemaCacheDuration' => 60,
//'schemaCache' => 'cache', ];
